Western blot analyses to evaluate the effect of Chamaecyparis obtusa (CO) extracts on the expression of peroxiredoxin- (Prx-) 1, heme oxgenase- (HO-) 1, catalase (CAT), and cyclooxygenase-2 (COX-2) in the presence or absence of hydrogen peroxide (negative control), H₂O₂ control (positive control), and 0.001%, 0.01%, and 0.1% CO extract groups. β-Actin was used as an internal control. (a) One representative data set obtained from among three individual experiments is shown. (b) Western blot band intensity analyses (relative ratio of signal/β-actin) are shown. ^∗P < 0.05 compared with the control group. ^†P < 0.05 compared with the H₂O₂ control group. ^‡P < 0.05 compared with the 0.001% CO extracts group. ^§P < 0.05 compared with the 0.01% CO extract group.
